ios - 使用 twitter API 出现 401 未经授权的错误

对于这个 twitter API 请求，我总是收到 401 Unauthorized 响应。这很令人困惑，因为我有一个 Twitter session 并且正在签署请求。提前致谢。

    NSURL *retweetAPIURL = [NSURL URLWithString:[NSString stringWithFormat"https://api.twitter.com/1.1/statuses/retweet/%@.json", tweetID]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:retweetAPIURL];
request.HTTPMethod = @"OST";

if (self.twitterSession) {

    [self.twitterSession signRequest:request];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    operation.responseSerializer = [AFJSONResponseSerializer serializer];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        block(nil, responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        block(error, nil);
    }];

    [[NSOperationQueue mainQueue] addOperationperation];
} else {
    block([self createErrorWithMessage:NSLocalizedString(NSLocalizedString(@"TWITTER LOGIN ERROR", nil), nil)], nil);
}

Best Answer-推荐答案

您确定正在签署请求吗？为什么不直接使用 SLRequest？

NSURL *retweetAPIURL = [NSURL URLWithString:[NSString stringWithFormat"https://api.twitter.com/1.1/statuses/retweet/%@.json", tweetID]];
ACAccount *account = // ...;
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:retweetAPIURL parameters:nil];
request.account = account;

NSURLRequest *preparedURLRequest = [request preparedURLRequest];

// create your AFHTTPRequestOperation using preparedURLRequest
